A couple of things come to mind:

1. Remembering how crappy I felt when I was 265 lbs.

2. Remembering my old friend Pete. He was pretty thin, had a diet like yours and rode a lot. (FInteresting you mention cream based soup. One day a small group of us followed Pete on an 80+ mile ride to Baltimore for dinner. We stopped for Maryland Crab Soup along the way. Pete got the New England style. The rest of us got the Manhattan style.) One fine February morning Pete suffered a massive heart attack a mile into a club ride. An EMT was driving by and began administering CPR within one minute, but he was too far gone.
